          Severity: normal
    Classification: Unclassified

Source games (Garry's Mod, Portal) segfault, with last good commit being
4e84f39 and last known bad ab2da98 (5442c0e is bad, too, mesa = libGL*, without
radeon_dri) I don't have enough time at this week, so I can't bisect this now.

That's quite strange, no Mesa calls at all, yet new Mesa definitely breaks
things...

I've just checked this on Intel (I have hybrid graphics) with same results. I
don't really know where non card-specifin bugs should go, sending it to Mesa
core...

Oh, and I'm using x86_64 system with 32-bit libs for games.
